Effect of simplified exercise program on quality of life, biomarkers, pain and muscle strength of individuals with knee osteoarthritis.
Trial report in Einstein (Sao Paulo, Brazil), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT02964624 (Response of Osteoarthritis Biomarkers After a Rehabilitation Program), which is not on this map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

Abstract
objectiveTo evaluate a simplified exercise program for patients with knee osteoarthritis in terms of pain, functionality, muscle strength, and quality of life. The correlation of serum levels of molecules and cytokines was evaluated after the exercise program.
methodsOverall, 47 patients with knee osteoarthritis participated in this single-arm interventional study. Outcomes were assessed using the Western Ontario and McMaster Universities Osteoarthritis Index, Quality of Life, Visual Analog Scale, Timed Up and Go functional test, and muscle strength assessment. Serum levels of molecules and cytokines were analyzed using enzyme-linked immunosorbent assays.
resultsThe program resulted in improvements in pain and physical function (0.21 points; 95%CI=-0.26; -0.17), Visual Analog Scale (1.50; 95%CI=-1.90; -1.10), EuroQol-5 Dimension 3-Level (0.16; 95%CI=0.100; 0.227), and Timed Up and Go test (0.40; 95%CI=-0.57; -0.23). Significant differences were noted in the isokinetic knee flexion peak torque (0.16; 95%CI=0.10; 0.22), isometric knee extension (0.31; 95%CI=0.20; 0.43), and flexion (0.18; 95%CI=0.12; 0.23) peak torques for osteoarthritis. However, there was no significant difference in serum biomarker levels after the program, and there was no correlation between serum biomarker levels and clinical improvement outcomes.
conclusionThe simplified exercise program for patients with knee osteoarthritis patients effectively improved pain, functionality, muscle strength, and quality of life. However, biomarkers do not provide evidence of clinical improvement. CLINICALTRIALS.GOV IDENTIFIER: NCT02964624.
